ok, I've had ( what feels like) a slight loss in power, I have very little , if any, boost in 1st and boost doesnt seem to come on until around 3500 - 4000 in other gears and my car feels slow even though the boost gauge goes through to 10psi without a problem. I checked all the connections etc... and found nothing busted or split but what I did find was oil around the area where the Y-pipe connects to the primamry turbo ( see pic) , could this be my problem???


oh and I'm running non-Seq

 

could be faulty solenoid or 1 way valve,had the same problem before, it was solenoid.

 

D'you give that bolt a twist? It doesn't look bad in the picture to me.

 

has anyone got a Non-seq diagram showing what solenoid/ valves I should check?

 

I recommend ordering a new metal gasket and installing it. That is a pressurized connection, and may be giving you a boost leak.

 

thats kinda what I thought considering there's a build up of oily resedue there, time to call Mazda

 

Sorry mate I didnt notice you're non-seq....wont be the solenoids then.You in Auckland area?

 

na I'm in chch
